The utility model discloses a kind of thermal spraying spray gun combined type powder feeding mouth structure, including powder-feeding mouth inner core and hollow external thread sleeve joint, the powder-feeding mouth inner core for it is horizontal " in " font structure, two ends outer wall is smooth structure；The inwall of the hollow external thread sleeve joint is that smooth structure, outer wall are external thread structure, and the internal diameter size and the outside dimension at the powder-feeding mouth inner core two ends of the hollow external thread sleeve joint match；One end of the hollow external thread sleeve joint is provided with sealing ring, and the sealing ring is integral type structure with the hollow external thread sleeve joint.The utility model constitutes the powder feeding mouth structure of complete set using two separate parts after combination, simple in construction, easy to assembly, it is possible to achieve quick-replaceable, and cost of manufacture is greatly lowered.
Description
Technical field：
The utility model is related to a kind of spray gun powder feeding mouth structure, more particularly to a kind of thermal spraying spray gun combined type powder-feeding mouth
Structure.
Background technology：
The powder-feeding mouth of thermal spraying spray gun is a kind of consumptive material, after certain use time, powder-feeding mouth can by flame ablation,
It can also be worn and torn simultaneously by powder, general powder feeding mouth structure is that the externally threaded stainless steel tube of band of integral hollow is made, every time more
, it is necessary to which whole powder-feeding mouth is reversely back-outed by screw thread when changing, the powder feeding nozzle assembly of damage is entirely changed, on the one hand, this
Threaded powder-feeding mouth workmanship complex process, high processing costs, whole change can increase considerably the use cost of user, another
Internal thread jack on aspect, this spray gun, after multiple stubborn silk, is easily destroyed internal thread, causes powder-feeding mouth to be twisted not tight.
Utility model content：
Technical problem to be solved in the utility model is：A kind of thermal spraying spray gun combined type powder feeding mouth structure is provided, can
To realize quick-replaceable, and cost of manufacture is greatly lowered.
The utility model is for the technical solution adopted for solving the technical problem：
A kind of thermal spraying spray gun combined type powder feeding mouth structure, including powder-feeding mouth inner core and hollow external thread sleeve joint, institute
State powder-feeding mouth inner core for it is horizontal " in " font structure, two ends outer wall is smooth structure；The hollow external thread sleeve joint it is interior
Wall is that smooth structure, outer wall are external thread structure, the internal diameter size of the hollow external thread sleeve joint with the powder-feeding mouth
The outside dimension at core two ends matches；One end of the hollow external thread sleeve joint is provided with sealing ring, the sealing ring with
The hollow external thread sleeve joint is integral type structure.
The internal diameter of the outside dimension of the sealing ring and the barral of a gun of thermal spraying spray gun matches.
The powder-feeding mouth inner core is processed by stainless-steel pipe；The hollow external thread sleeve joint is added by brass material
Work is formed.
Implementation process of the present utility model：
1. stainless steel tube is made into powder-feeding mouth inner core；
2. the hollow external thread sleeve joint of a powder-feeding mouth inner core is made of brass, is external thread structure；
3. an internal thread endoporus is got out on thermal spraying spray gun；
4. internal thread endoporus stainless steel powder-feeding mouth inner core inserted on spray gun, then again the hollow external thread sleeve of brass
Joint is also screwed into the internal thread endoporus of spray gun, and thus powder-feeding mouth is fixed on spray gun.
The utility model is using two independent parts：Stainless steel powder-feeding mouth inner core and the hollow external thread sleeve of brass connect
Head, constitutes the powder feeding mouth structure of complete set after combination, simple in construction, easy to assembly, it is possible to achieve quick-replaceable, and makes
Cost is greatly lowered.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of powder-feeding mouth inner core in Fig. 1；
Fig. 3 is the structural representation of hollow external thread sleeve joint in Fig. 1.
Embodiment：
The utility model is further explained below in conjunction with the accompanying drawings and explanation：
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of thermal spraying spray gun combined type powder feeding mouth structure, including powder-feeding mouth inner core 1 and hollow
External thread sleeve joint 2, the powder-feeding mouth inner core 1 for it is horizontal " in " font structure, two ends outer wall is smooth structure；It is described hollow
The inwall of external thread sleeve joint 2 is that smooth structure, outer wall are external thread structure, the internal diameter chi of hollow external thread sleeve joint 2
The very little outside dimension with the two ends of powder-feeding mouth inner core 1 matches；One end of hollow external thread sleeve joint 2 is provided with sealing ring 3,
Sealing ring 3 is integral type structure with hollow external thread sleeve joint 2.
The internal diameter of the outside dimension of sealing ring 3 and the barral of a gun of thermal spraying spray gun matches.
Powder-feeding mouth inner core 1 is processed by stainless-steel pipe；Hollow external thread sleeve joint 2 by brass material process and
Into.
Implementation process of the present utility model：
1. stainless steel tube is made into powder-feeding mouth inner core 1；
2. the hollow external thread sleeve joint 2 of a powder-feeding mouth inner core is made of brass, is external thread structure；
3. an internal thread endoporus is got out on thermal spraying spray gun；
4. internal thread endoporus stainless steel powder-feeding mouth inner core 1 inserted on spray gun, then again the hollow external thread sleeve of brass
Cylinder joint 2 is also screwed into the internal thread endoporus of spray gun, and thus powder-feeding mouth is fixed on spray gun.
The utility model is using two independent parts：Stainless steel powder-feeding mouth inner core 1 and the hollow external thread sleeve of brass connect
First 2, the powder feeding mouth structure of complete set is constituted after combination, it is simple in construction, it is easy to assembly, it is possible to achieve quick-replaceable, and make
It is greatly lowered as cost.
